+1 Rob I have seen number of MBH networks using DSCP to change forwarding - AKA PBR..
The question is really - what is here to standardize? RSVP-TE use cases mentioned by Rob (CBTS/PBTS in IOS realm) are classical examples of Policy Based Routing and as such are subject to implementation details, not standardization. Am I missing something?
